AbstractLibrary

abstract class AbstractLibrary : AbstractPluggable, Library

Base Library implementation defaulting every contribution (operators, clauses, primitives, functions) to empty, and providing structural equals/hashCode/toString; subclasses only need to override Library.alias plus whichever contributions they actually provide.

Properties

alias

abstract val alias: String

The alias identifying this library

clauses

open override val clauses: List<Clause>

Rules, facts, or directories to be loaded by a solver when the library is used

functions

open override val functions: Map<Signature, LogicFunction>

LogicFunctions to be loaded by a solver when the library is used, indexed by their Signature in the eyes of the solver

operators

open override val operators: OperatorSet

Operators to be loaded by a solver when the library is used

primitives

open override val primitives: Map<Signature, Primitive>

Primitives to be loaded by a solver when the library is used, indexed by their Signature in the eyes of the solver

rulesSignatures

open val rulesSignatures: Sequence<Signature>

The Signature of every Rule (i.e. non-fact clause) among clauses, deduplicated.

Functions

contains

open operator fun contains(operator: Operator): Boolean

Checks whether this library contains the definition of provided operator

open operator fun contains(signature: Signature): Boolean

Checks whether this library contains the provided signature.

equals

open operator override fun equals(other: Any?): Boolean

getAllOperators

fun Library.getAllOperators(): Sequence<Operator>

Shorthand for this Library's declared Library.operators, as a Sequence.

hasFunction

open fun hasFunction(signature: Signature): Boolean

Checks whether this library has a LogicFunction with provided signature

hashCode

open override fun hashCode(): Int

hasPrimitive

open fun hasPrimitive(signature: Signature): Boolean

Checks whether this library has a Primitive with provided signature

hasProtected

open fun hasProtected(signature: Signature): Boolean

Checks whether the provided signature, is protected in this library

hasRule

open override fun hasRule(signature: Signature): Boolean

Checks whether this library has a Rule with provided signature

plus

operator fun Library.plus(other: Library): Runtime

Combines this Library and other into a two-library Runtime, via Runtime.of. Note that, unlike Runtime.plus, this does not reject a clashing Library.alias: if both share the same alias, other silently wins.

toRuntime

fun Library.toRuntime(): Runtime

Converts the current library into a Runtime containing a single library

toString

open override fun toString(): String
